S. D. STOUT, OF CHARLESTON, TENNESSEE.

PUMP.

Specification of Letters Patent No. 30,363, dated October 9, 1860.

To all whom it may concern:

Be it known that I, S. D. STOUT, of Charleston, in the county of Bradley and State of Tennessee, have invented a new and Improved Force-Pump; and I do hereby declare that the following is a full, clear, and exactV description thereof, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a perspective view of the improved pump with the front plate of the valve box removed, exhibiting the arrangement of valves and section pipes. Fig. 2 is a horizontal section through the cut-off box.

Similar letters of reference indicate corresponding parts in both figures.

This invention belongs to that class of pumps in which the valve box is submerged, under water, and in which compressed air is made to operate upon the water and force it upward from the valve box without using pistons or anything of the kind.

My invention and improvement consists in the employment of compressed air in a novel manner for forcing water up through a pipe from the bottom of a well or other low level, in a continuous stream as will be hereinafter described.

The invention further consists in the use of a vibrating cut-off for conducting air alternately into the two side compartments of the valve box, as and for the purpose hereinafter to be described.

To enable those skilled in the art to fully understand my invention I will proceed to describe its construction and operation.

A is a box of a suitable capacity divided by two partitions into three apartments a, (if, and c2, the two c, c?, are about double the capacity of the central apartment c', and these two side chambers each have a valve Z), in their bottom, opening upward and allowing the water into which the box is submerged to enter through the orifices which the valves close and fill these two outer chambers but notat the same time, as will be hereinafter explained. The chambers a, c2,

communicate with the central chamber a', by orifices through the partitions, which orifices are closed by a double puppet valve d, that is operated by the force of water entering the chamber a, so that when one orifice is open the opposite one will be closed tightly. From chamber a', is an escape pipe B, which leads up from near the bottom of the chamber a', any desirable distance.

C, C are air pipes which communicate with the side chambers a, a2. These two latter pipes are carried up any required height, and secured to a horizontal circular plate D, which is covered by a circular box or cut-off E, that is packed tightly on the top of plate D, but not so tight as to prevent it from being moved on the plate by the handle Il.. The boxwE, is divided into two chambers, one of which is air tight, and the other communicates with a bellows or force pump G, by a tube H, Fig. l. The movement of the box E, is limited by a fixed pin c, that projects from the plate D, and works in a slot f, seen in Fig. 2, so that at each full movement of the box, the hole m, that passes through the box` forms a communication between one of the chambers u, u2, and the outer air, at the same time the other chamber is made to communicate with the bellows through the tube H.

From this description it will be seen that by placing the valve box A, into the water, the water will rushl into both chambers a, a2, and till them, then by forcing air by means of the bellows Gr, down one of the pipes C, into the chamber c, the waterA in this chamber will be forced into the central chamber fz, through the valve orifice in the partition. Then by reversing the cut-off box E, the air will be forced into the chamber a', from chamber a?, while the chamber a, is lling again with water. By this alternating pressure of air into first one chamber a, and then the other a2, the water is forced from both chambers into the central chamber a', and from it up through pipe B.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent is The three chambered box A, with its valves 7), 7), and d, and leader pipe B, in combination with the air pipes C, C', cut-off box E, and bellows Gr, or its equivalent; the whole being arranged substantially as and for the purposes herein described.
